3. H/W SETUP

25) System Warning Speaker Connector (4-pin SPEAKER)

This 4-pin connector connects to the case-mounted speaker. You may leave this

disconnected if you connect the chassis speaker to the internal speaker connec-

tor. All three sources (LINE_OUT, INT_SPKA, SPEAKER) will allow you to

hear system beeps and warnings. Only LINE_OUT will allow you to hear sys-

tem beeps before the integrated audio has been properly initialized.

26) Keyboard Lock Switch Lead (2-pin KEYLOCK)

This 2-pin connector connects to the case-mounted key switch to allow key-

board locking.

27) System Power LED Lead (3-1 pin PLED)

This 3-1 pin connector connects the system power LED, which lights when the

system is powered on and blinks when it is in sleep mode.

28) Reset Switch Lead (2-pin RESET)

This 2-pin connector connects to the case-mounted reset switch for rebooting

your computer without having to turn off your power switch. This is a preferred

method of rebooting to prolong the life of the system’s power supply.

29) ATX Power Switch Lead (2-pin PWRSW)

The system power is controlled by a momentary switch connected to this lead.

Pressing the button once will switch the system between ON and SOFT OFF.

Pushing the switch while in the ON mode for more than 4 seconds will turn the

system off. The system power LED shows the status of the system’s power.

30) System Management Interrupt Lead (2-pin SMI)

This allows the user to manually place the system into a suspend mode or “Green”

mode, where system activity is decreased to save electricity and expand the life

of certain components when the system is not in use. This 2-pin connector con-

nects to the case-mounted suspend switch. If you do not have a switch for the

connector, you may use the “Turbo Switch.” SMI is activated when it detects a

short to open moment and therefore leaving it shorted will not cause any prob-

lems. This may require one or two presses depending on the position of the

switch. Wake-up can be controlled by settings in the BIOS but the keyboard will

always allow wake-up (the SMI lead cannot wake up the system).

31) Message LED Lead (2-pin LED)

This indicates whether a message has been received from a fax/modem. The

LED will remain lit when there is no signal and blink when there is data transfer

or waiting in the inbox. This function requires ACPI OS and driver support.
